Ferrites are high resistivity materials made of MnZn or NiZn plus iron oxides. They derive their magnetic properties by complex interaction of metallic and nonmetallic elements. They are available as bars, toroids, pot cores etc. They are used in inductors, transformers, etc by power electronics industry.
MnZn (MnxZn1-xFe2O4 ) ferrites saturate at higher flux density (0.3 to 0.5 T). Their permeability is high (mi = 500 to 20,000). But their resistivity is low. So Mn Zn ferrites are used upto 1 MHz.
NiZn (NixZn1-xFe2O4) ferrites offer lower saturation (<0.35T). Their permeability is low (mi = 10 to 2000). But their resistivity is high. So NiZn Ferrites are used in 1 MHz to 0.5 GHz range.
